Slab Leak Myths: 8 Things Homeowners Get Wrong
Some of what circulates about slab leaks is half right. Here are eight common beliefs and what is closer to the truth.
1. “A warm floor always means a slab leak”

No. Sun, ducts and appliances warm floors too. See warm spot on floor.
2. “The warm spot is where the leak is”
Not exactly. Hot water travels, so the warm area can sit away from the break. See slab leak detection.
3. “A slab leak always means breaking the floor”
No. Reroutes and some lining avoid it. See repair options.
4. “A small leak can wait”
It will not fix itself. See can a slab leak fix itself.
5. “Insurance always pays”
It depends on the policy, and the pipe itself is often excluded. See slab leak insurance coverage.
6. “Only old houses get slab leaks”
Age is a factor, but not the only one. See causes of slab leaks.
7. “A high bill means a slab leak”
It can, but irrigation, a running toilet or a change in use can too. See high water bill and slab leaks.
8. “Any plumber can find it”
Locating leaks takes testing equipment and experience. See hiring a slab leak plumber.
